If you're saying there's enough tolerance built in for the BCG to rub on the lower if it's pushed up what's to stop that if there not a wedge?
That terrible slop that all of you are trying so vehemently to get rid of
No, I stated that it “can” happen, and not “will”.
My professional opinion on the AR that I saw it happen to is that something was out of spec, or there was a case of “stacking tolerances”, which produced a fit sloppier than most.
Without the Accu-Wedge, the loose upper and lower fit were not causing an issue. The gun functioned as it was meant to.
Without the Acu-Wedge to forcing the parts together, the violence of the action cycling all by itself would force the parts APART and keep the malfunction from happening.
To the owner, it was ”rattley” and annoying. He installed an Accu-Wedge, which made it short cycle with every single round fired, due to the carrier dragging on the inside top of the receiver extension.
When I cycled it by hand, I could readily feel the carrier dragging, but I wasn’t exactly sure what it was. Field stripping allowed me to see the wear marks that were starting.
Removed the Accu-Wedge, and the AR ran perfectly for the rest of the day.
To clarify, if all parts are within spec (to include the upper and lower receivers) then using an Accu-Wedge should not cause the carrier to drag on the receiver extension. In that case, my main worry would be pieces of the Accu-Wedge breaking off and falling down into the fire control group. That is something that I have seen on multiple occasions. On another occasion, I saw pieces of the Accu-Wedge migrate into the receiver extension, causing short cycling.
So it just happens some of the time. Cool.
You didn't describe it thoroughly unless you edited that post also.
Better explanation. I wasn't attacking your professional ability, just trying to get more details. Seems like you got a little sensitive in this thread. Apologies.
I completely agree that they don't do a thing for accuracy, but to state that a piece of silicone ****ed that rifle up is false.
I have accepted that they don't do much for accuracy from my own testing. I like a solid slop free rifle. Preference not necessity.
It suffered a loss of concentricity.
